TC PC Subsystem Bench is a comprehensive 5-subsystem hardware performance benchmark and system telemetry suite for Linux desktops and workstations.

An independent Linux alternative inspired by PassMark PerformanceTest for evaluating overall computer performance across compute, graphics, memory, and filesystem storage workloads with reproducible scoring and visual charts.

Genuine Linux Benchmark Subsystems Implemented:

• CPU Mark: Multi-threaded and single-threaded prime number sieving, SHA-256 and PBKDF2-HMAC cryptography, floating-point N-body matrix math, and zlib/bz2/lzma data compression throughput.
• 2D Graphics Mark: Offscreen QPainter vector line bursts, anti-aliased cubic Bezier splines, alpha-blended gradients, and multi-size typography rendering onto QImage surfaces.
• 3D Graphics Mark: Software-projected 3D polygon mesh pipeline featuring subdivided icosphere and torus geometry, directional Gouraud shading, depth sorting, real-time FPS, 1% Low FPS, and triangles-per-second metrics.
• Memory Mark: Real buffer allocation measuring sequential 64-bit read/write bandwidth, block copy MB/s, and pointer-chasing random access latency (ns) alongside live /proc/meminfo telemetry.
• Disk Mark: Safe temporary file sequential read/write and random 4K IOPS benchmarking on any mounted user directory with automatic cleanup, plus CSV, JSON, and TXT report export.
